In fields such as food testing, traditional Chinese medicine research and development, environmental monitoring, and materials analysis, the efficient extraction of target components from complex samples is a crucial prerequisite for subsequent qualitative and quantitative analysis. ...
Polymers are the foundation of countless modern applications, from automotive components to medical devices. Ensuring the integrity of raw materials, optimizing production processes, and maintaining product purity are essential to achieving high-performance polymers. Fourier-transform near-infrared (FT-NIR) spectroscopy is an indispensable tool for polymer manufacturers, providing rapid, ...
HFEs were introduced as alternatives to traditional solvents due to increasing environmental concerns and the growing demand for safer chemical products. ...
Solid adsorption/carbon disulfide analysis needs solvent parse, causing environmental pollution and a great harm to human body. Therefore, air samples are usually pretreated by SUMMA tank sampling/freeze preconcentration and adsorption tube sampling - thermal desorption, with the advantages of no solvent pollution, simple operation, rapid ...
In order to achieve a good exhaust gas emission effect and reduce the pollution of the surrounding environment, after a long-term control and treatment of pharmaceutical and chemical solvents, the exhaust gas emission index has been better reduced. Pharmaceutical and chemical waste gas control effect For most pharmaceutical and chemical enterprises, it is necessary to ...
Wipe samples were collected by the client and sent to Sitelab's laboratory for analysis in order to monitor and adjust a new cleaning system installed. ...
Abstract This application note adopted the Full Evaporation Technique (FET) to analyze the solvent residual, based on California Residual Solvents Category, in cannabis oil by a CDS Analytical 7000C concentrator equipped with a dynamic headspace (DHS) module. ...

It should also be noted, that US EPA 5035 includes the handling of soils which exceed normal VOC concentration levels (greater than 200 ppb).1 Introduction US EPA Method 5035 allows for two soil sample collection options that can be used in accordance with US EPA Method 8260C: “The first option is to collect an appropriate sample volume in a pre-weighed vial with a septum-sealed screw-cap ...
These processes require the use of several harsh organic solvents, like methanol, hexane, acetonitrile, and chloroform, all of which can affect the integrity of your label’s adhesive and cause your printout to fade or rub off entirely. Cannabis samples also need to be tested for potentially harmful contaminants, including pesticides, heavy metals, and residual ...
